I think Sabarmati BG is now major terminal station so only train passing through toward Vadodara coming from Meshana will required it so railways is no constructing it instead of their their is major requirements of doubling between Chandlodiya B (Cabin) and Khodiyar, Y-section between Sabarmati Bridge and Asarva (bypassing Ahmedabad Jn.) and Y-section between Gandhigram and Chandkheda Road (bypassing Sabarmati D)
